Hi Yun,

Thanks again for the pointer to ZooKeeper. I think it's a very interesting project and looks like a great way to solve the worker sync problem we face with Orchestration.

One thing that wasn't clear to me immediately was the benefit of using something like ZooKeeper vs doing row-level db locking (where the row is the transaction state)?

Perhaps you could elaborate on that a little?
